SPATIAL SENSE: 3-D FIGURES
REMEMBER!
Pyramids and prisms are grouped by the shapes of their bases.
A pyramid has one base. A prism has two bases which are the same (congruent).
Square-based pyramid
Pentagonal-based pyramid
Rectangular-based prism
Triangular-based prism
1. Connect each 3-dimensional solid to its name. One has been done for you.
Cone
Pentagonal-based prism
Cylinder
2. Shade the base(s) of each 3-D solid and state
whether it is a prism or pyramid.
3-D Solid
Hexagonal-based pyramid
Cube
Sphere
3. Complete the chart by neatly drawing the base(s) of
each pyramid or prism.

Did You Know?
A tetrahedron is a
special triangular-based
pyramid. Each of its four
faces is identical and has
all sides (edges) equal.
4. Print the names of two real items that have the following shape.
a) Rectangular-based prism
b) Cylinder

7. Name and draw the 3-D solid with the following faces.
Faces
A face is a flat surface, like
a floor or the top of a box.
An edge is a “line” where
two faces meet.
A vertex is a “point” or corner where several faces
and edges meet.

8. In her history class, Joanne learned that the Egyptians built large structures as tombs for their Pharaohs.
These structures were very different from those which we see today. Each usually had a square base and four
triangular faces that met at a point. What 3-D solid did the Egyptian build?
